Limited Slip - Necessary?

I'm trying to spec out an X, and I'm not car savvy enough to know what a limited slip differential is for. Some people have told me that it makes only the wheel that has traction spin, which is good when you're stuck. If this is true, then is it really necessary when you have 4 wheel drive?

since you are in Florida, it wont make much since unless you do alot of driving in mud. Limited slip especially comes in great during winter weather like snow and icy roads. even in 4wd, it helps in those conditions. if you are just going to road ride your JK with a little off- pavement use, you will be fine without the LS.

Ok, that's good to know. One other question - on the Jeep.com site, if you click on the information for the limited slip, it lists the Dana 44 rear axle. Does this mean you get the D44 if you order the limited slip, or is this a misprint on the page?

It's a very inexpensive upgrade. You'll wish you had it the day you discover you actually own a 2 wheel drive - One in the front and one in the rear.
My last 4x4 was a Toyota Truck with open differentials. I was amazed at how you could get stuck crossing very small obstacles on a diagonal line - on level ground! Get the limited slip!

It is worth it if you don't plan massive drivetrain upgrades.

You already will have an electronic limited slip - that is actually quite effective. If I were to upgrade from that - a selectable locker in the rear is probably a better option as far as offroad performance and handling goes.

In an FJ - this ATRAC electronic limited slip does work quite well just for that case. New Wrangler has a similar system.

Ok, with the electronic slip, it sounds like I will be alright without the mechanical. The only reason I would order it at this point is if you get a Dana 44 rear axle by ordering it. But, I'm not sure if that's just a misprint or what.

I don't see that. When you order the Tow Group, that includes the rear Dana 44 and 4.10 gearing. But the Limited Slip option is all by itself.

It's when you're going through the configurator. On the options tab, you can actually click on each option to get a little more info. The limited slip detail mentions the dana 44. BUT, in my case this is all irrelevant if the dana 44 comes with the tow package, as I will be getting that for sure.

But your old durango didn't have brake assisted traction control like the JK does.

For $260 it seemed like a no-brainer option for me.

I believe the e-LSD just applies the brake to slow the spinning wheel.

The mech LSD actually transfers power. As previously stated, a 2WD w/ LSD can often out perform a 4X4 without.
